Levi'sMen's Barstow Western Standard Shirt

Can anyone tell me the measurements for the sizes large or XL. I'm buying as a gift so i was hoping someone could help

What’s the sizing like? My fella is a large, large and he likes quite roomy oversized

It says: fastening button, but pic shows snaps. Which is it, please?

Hi all, does this shirt fade? I'd prefer if it did
